THERMAL MANAGEMENT
H e a t s i n k C o o l i n g
The unique heatsink on
your POWERCLASS™
amplifier has been designed with fins on the
inside of the aluminum mass. This allows for the
transfer of heat from the
circuitry to the heatsink fins and out through the vents in the endplates. Be sure you have ample space around the amplifier for cooling, at least 2" on all sides.
Forced Air Thermal Management
To manage the additional heat associated with higher output capability, a thermally controlled fan has been designed into the PC1800. When the heatsink temperature reaches a predetermined value, the fan is activated and cool air is drawn in through the lower intake vents on the endplate. This cool air flows below the circuit
board, through the fan and across the internal fins, cooling the heatsink. The warm air is
then forced out through the upper endplate exhaust vents.
